They don't require darkness to occur -- they simply don't depend on light.The light reactions absorb light and harness the energy to powder electron transfers.Even books and journals are introduced in this link.

Most photosynthetic organisms capture visible light, although there are some that use infrared light.
Products of these reactions are adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide phosphate (NADPH).
Dehydration synthesis is also used to convert glucose to starch, which plants use to store energy.
The overall chemical equation is a summary of a series of chemical reactions. The light reactions require light (as you might imagine), while the dark reactions are controlled by enzymes.
Many reactions occur, but the overall chemical reaction for photosynthesis is: In a plant, the carbon dioxide enters via leaf stomates by diffusion.
Water is absorbed through the roots and is transported to leaves through the xylem.Actually, plants reserve very little of the glucose for immediate use.Glucose molecules are combined by dehydration synthesis to form cellulose, which is used as a structural material.Oxygen is also produced by the plant in this cycle, which is then let off into the air!Have you noticed how clean and pure the air feels when there are plants around? Photosynthesis reduces carbon dioxide into carbohydrates, \[\ce\] Thus, both electrons and energy are required.The electrons come from water molecules, and the energy is first absorbed by pigments known as chlorophylls and carotenoids.In plant cells, the light-dependent reactions occur in the chloroplast thylakoid membrane.The overall reaction for the light-dependent reactions is: In the dark stage, ATP and NADPH ultimately reduce carbon dioxide and other molecules. The process of photosynthesis takes place in the chloroplasts (chloro = green; plasti = formed, molded), specifically using chlorophyll (phyll = leaf), the green pigment involved in photosynthesis.As early as 1640, people have demonstrated that photosynthesis was a means of converting carbon dioxide in the air into plant material.
